Will I be alright?

I just bought this GPU last nigt: MSI N660 TF 2GD5/OC GeForce GTX 660 2GB 192-bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card - Newegg.com

I'm wondering if I'm going to have a powerful enough PSU to run it.

I opened my case and it says my PSU is 460W. With 12Va, 12Vb, and 12Vc. (I'm guessing that means I have 3x 12V rails?)

Upon looking into the card a bit, it says that only a 450W power supply is needed. I'm almost certain that I'll be ok, but I always like to double check with people that know more than I do.

Any info will be appreciated. Thanks.

What's the brand on the PSU? Wattage and rails/amps aren't the only thing to worry about.

Well it's from HP, and there's an HP sticker on it. So I guess it's an HP PSU?

You should be alright. I wouldn't OC at all though.

Thanks a ton man. I gave you a "thanks". The card already comes pre-OC. I hope that won't be an issue.

Well I meant further than from the factory and CPU too. Although being a pre-built OCing the CPU probably won't happen but needed to be said.

Yep, thanks again. I'm not too power-hungry when it comes to my PC. I just wanna be able to game reliably.

I suggest a Seasonic or Corsair replacement sometime in the near future to be on the safe side.
